OK, here's one for getting rid of bad luck. If you spill salt, which is supposed to indicate a bad spirit hanging around you causing trouble, Or your having a string of bad luck throw salt over your left shoulder. The Spirit will go after the salt crystals and forget about bothering you.
OH, and here's one about vampires. If your ever attacked by a vampire throw sand at his feet. He will be compelled to count all the grains and you can run away while he is occupied.
Any one else know superstition about the supernatural?
